Easy-to-use free crypto tool for cross-platform mail

Ciphire Mail came out today, free for nonprofits, private users and the press. Oxblood sez,

t's a powerful and easy-to-use email encryption client that was designed for non-technical users. Most people don't realize that sending email across the Internet is like sending a postcard written in pencil in the real world. That's a pretty scary thought. And even if you've got nothing to hide, you've got plenty to protect, like personal photographs, medical and financial information, and maybe even love letters.

Ciphire Mail was three years in development and has been peer-reviewed by some of the world's leading cryptography and security experts. The whole purpose of the technology is to bring the highest level of security to all email users, regardless of computer skills. Once Ciphire Mail is installed it operates something like a virus scanner, just working quietly in the background.
